Hi @SITARAM 

Could you please reproduce the issue on reference board: nucleo or eval??  try uninstalling the winUSB driver from the device manager and then reinstalling it using Zadig.

If the firmware has a proper "Microsoft descriptor" for winusb, it does not need Zadig. Microsoft-signed drivers have precedence over any self-signed package. So just use libusb API library that works via the winusb driver. For more info please visit the Microsoft Q&A forum.
